人工椎间盘生物摩擦学研究进展:脊柱模拟试验机方法

Research Progress on Biotribological Studies in Artificial Disc Prosthesis: The Method by Using Spinal Simulators

人工椎间盘生物摩擦学性能评估有多种研究方法,其中使用脊柱模拟试验机是评估椎间盘假体中长期磨损性能的主要手段.本文整理了近年来使用脊柱模拟试验机进行椎间盘假体磨损性能评估的研究文献,介绍了现有脊柱模拟试验机种类和研究方法以及相关试验标准;分析了近年来针对影响假体磨损性能主要因素(假体结构设计、关节材料、材料表面处理、载荷/运动/频率、润滑液、磨损时间等)所取得的研究进展;综述了主要颈腰椎人工椎间盘假体的磨损性能.

A lot of methods have been used for evaluation on biotribological performance in artificial disc,one of them is the application of spinal simulators,which has been widely used to study the medium and long-term wear performance of disc prosthesis.This review showed the current literatures regarding to the study about the wear performance in disc prosthesis by using spinal simulators,introduced the types of spinal simulators,research methods as well as relative test standards.In particular,it also presented the updated information about the research progress on effect factors of wear performance in disc prosthesis（structural design,materials for joint prosthesis,surface treatment,load/motion/frequency,lubricating liquid,wear time,etc.）,and summarized some research results about wear performance in cervical/lumbar artificial disc prosthesis.
